Is Exilis Something You Can Do if You Have Stainless Steel Hardware in Your Body?

I know that I've been told that I can't have some of the radio wave procedures because if the stainless rod in my back from surgery in 1981. I'm looking at having the procedure done on my upper arms. I also was told that I couldn't have an MRI, but just had a 0.3 Tesla one done with no ill effects. I cannot have one stronger than that due to heating of the steel rod. I am only 45 and 5'6" and 144# but due to early menopause my skin elasticity is terrible and I want to smooth out my upper arms.
